Irrlicht - "unsupported texture format" [solved]

[FTC]

Hi,

i am new to cegui, so I was trying to setup a very basic interface with irrlicht. Through searching and tutorials I got this far:

Code: Select all

    IrrlichtDevice *device =createDevice(EDT_OPENGL, dimension2d<u32>(640, 480), 16,false, false, false, 0);
    CEGUI::IrrlichtRenderer *myRenderer = &CEGUI::IrrlichtRenderer::bootstrapSystem(*device);
    CEGUI::SchemeManager::getSingleton().create("TaharezLook.scheme");
    CEGUI::WindowManager& winMgr = CEGUI::WindowManager::getSingleton();
    CEGUI::Window* root = (CEGUI::Window*)winMgr.createWindow("DefaultWindow", "Root");
    CEGUI::FrameWindow* wnd = (CEGUI::FrameWindow*)winMgr.createWindow("TaharezLook/FrameWindow", "Demo Window");
    root->addChildWindow(wnd);


and of course

Code: Select all

        smgr->drawAll();
        CEGUI::System::getSingleton().renderGUI();
        driver->endScene();


I had to find out why the programm crashed several times (exceptions) but now it kind of runs. Except it does not work.
When using this

Code: Select all

    CEGUI::FrameWindow* wnd = (CEGUI::FrameWindow*)winMgr.createWindow("TaharezLook/FrameWindow", "Demo Window");

I get two "unsupported texture format" messages in the console and no gui displayed, Irrlicht runs like it should. I just use the files that were included in the package. Not finding the files does not seem to be the problem anymore, because that caused exceptions.
I use irrlicht 1.7.1 and Code::Blocks with mingw on Win XP.
Do I have to link another specifig image loader or something?

I think those texture messages are an issue in Irrlicht - I saw it mentioned on their forum - and are harmless and can be ignored (I get them too).

You have to set the gui 'sheet' to the root you created:

Code: Select all

CEGUI::System::getSingleton().setGUISheet( root );

Hi,

thanks I really missed that line in the tutorials somehow
However, I seem to have missed something else, because my windows looks like this:

There is no titlebar
Did I forget anything else?
That's the current code:

Code: Select all

    CEGUI::SchemeManager::getSingleton().create("TaharezLook.scheme");
    CEGUI::WindowManager& winMgr = CEGUI::WindowManager::getSingleton();
    CEGUI::Window* root = (CEGUI::Window*)winMgr.createWindow("DefaultWindow", "Root");
    CEGUI::System::getSingleton().setGUISheet( root );
    CEGUI::FrameWindow* wnd = (CEGUI::FrameWindow*)winMgr.createWindow("TaharezLook/FrameWindow", "Demo Window");
    root->addChildWindow(wnd);
    wnd->setPosition( CEGUI::UVector2( CEGUI::UDim( 0.25f, 0 ), CEGUI::UDim( 0.25f, 0 ) ) );
    wnd->setSize( CEGUI::UVector2( CEGUI::UDim( 0.5f, 0 ), CEGUI::UDim( 0.5f, 0 ) ) );
    wnd->setText( "Hello World!" );

Hmmm. Does the window react if you click / drag where the titlebar should be? I want to establish if the title bar is truly not there, or whether it's a rendering issue (which is most likely). It seems it's probably an issue with rendering to texture (you could confirm this by calling setUsingAutoRenderingSurface on the window and passing false).

Which hardware are you running on?

Hi,

setUsingAutoRenderingSurface did the trick for showing the rest of the window, however, for the windows skin, the window seems to be cropped somehow.
But this could also be due to my hardware. I currently run this on my old laptop, because my main pc is not available.
I run it on WinXP which itself runs on a Celeron M processor 1.6 ghz with 768 mb ram and an Intel Onbard Graphicscard. OpenGL seems not to be the favorite driver of that card, but my irrlicht dll has no directX driver.

Neither the window, nor the cursur does react, probably because I do not pass any events, yet. Or sould that be done by the system automatically?
[edit] Just read the input tutorial, I now have a reaction The window responds as it should, even with the titlebar not being drawn.

My full programm looks like this:

Code: Select all

#include <irrlicht.h>
#include <CEGUI.h>
#include <RendererModules/Irrlicht/CEGUIIrrlichtRenderer.h>

using namespace irr;
using namespace core;
using namespace scene;
using namespace video;
using namespace io;
using namespace gui;


int main(int argc, char** argv)
{

    IrrlichtDevice *device =
        createDevice(EDT_SOFTWARE, dimension2d<u32>(640, 480), 16,
            false, false, false, 0);

    CEGUI::IrrlichtRenderer *myRenderer =
       &CEGUI::IrrlichtRenderer::bootstrapSystem(*device);

    device->setWindowCaption(L"Hello World! - Window Test");

    IVideoDriver* driver = device->getVideoDriver();
    ISceneManager* smgr = device->getSceneManager();


    smgr->addCameraSceneNode();


    CEGUI::SchemeManager::getSingleton().create("TaharezLook.scheme");
    CEGUI::WindowManager& winMgr = CEGUI::WindowManager::getSingleton();
    CEGUI::Window* root = (CEGUI::Window*)winMgr.createWindow("DefaultWindow", "Root");
    CEGUI::System::getSingleton().setGUISheet( root );
    CEGUI::FrameWindow* wnd = (CEGUI::FrameWindow*)winMgr.createWindow("TaharezLook/FrameWindow", "Demo Window");
    root->addChildWindow(wnd);
    wnd->setPosition( CEGUI::UVector2( CEGUI::UDim( 0.25f, 0 ), CEGUI::UDim( 0.25f, 0 ) ) );
    wnd->setSize( CEGUI::UVector2( CEGUI::UDim( 0.5f, 0 ), CEGUI::UDim( 0.5f, 0 ) ) );
    wnd->setText( "Hello World!" );
    wnd->setUsingAutoRenderingSurface(false);

    CEGUI::System::getSingleton().setDefaultMouseCursor("TaharezLook", "MouseArrow");

    while(device->run())
    {
        driver->beginScene(true, true, SColor(0,200,200,200));

        smgr->drawAll();
        CEGUI::System::getSingleton().renderGUI();
        driver->endScene();
    }

    device->drop();

    return 0;
}

Can we confirm which version of CEGUI this is, please? If it's 0.7.2 or later, I think it could be driver related (not passing the buck - if you test it elsewhere, I'm confident it would work!). If it's an earlier version, we did fix some bugs where we were not correctly detecting capabilities correctly, so it could be that.

Hmmm. Then again, I see you're using the software renderer in irr, I think that definitely will affect things, since I only really test this stuff with GL/D3D. I'll add a ticket to remind me to test, and at least try to fix any issues that come up with the software renderer.

Hi,

I had the chance to test the gui on another pc, not much better than my pc, but the gui is working fine (with all skins). Software renderer does not work. I use 0.7.2.

Also, I found the CEGUI Layout editor and tested it. It wont even start on my laptop, but runs slowly on the other pc.

I think when my pc is useble again, the problems will be gone

greetings

Thanks for the update.

I shall make some attempt to get things working with the software driver if at all possible, though obviously it's not a priority

Hope all is well once your PC is usable.

Hi,

pc is repaired, everything works fine now
Using the software driver is still not possible (programm crashes).

greetings
